Title: Membrane expansion structure of low temperature gas tank
Inventor: KAWAGOE EIJI
IPC: F17C3/06
Filed: 1978-03-23
Abstract: PURPOSE:To increase hardness by specifying right-angled shapes of waved parts that cross at right angles. CONSTITUTION:Waved parts 8, 9 crossing at right angles are met at their center 11 so that a flat part 10 be surrounded by waved parts 8, 9, and folds 8', 8'', 9', 9'' are formed to connect waved parts 8, 9 at their section. Under this structure, the expansion and contraction of membrane 1 due to the heat performance of the tank is sufficiently absorbed by the folds 9'', 8'' set inside the outer folds 9', 8', since the axial expansion and contraction of waved parts 8, 9 cause the expansion and contraction of the outermost folds 9', 8' of the other waved parts 9, 8. Thus, no tolerance which might be caused by the expansion and contraction of folds in inner and outer directions is generated, and the desired goal is obtained.
